When on the road, most of the time, you need a quiet and peaceful time. If you have your music playing, you do not want interruptions from outside noises.

Good news! You can beat this problem with sound deadening sprays. Hang on as we look at how they ensure you have an excellent ambiance when driving.
Sound Deadening Spray for Cars: The Basics

This product’s elements are sound dampening materials suspended in a binding solution. When sprayed, the materials coat the surface.

We will guide you on how to apply this product. First, let us look at the tools you need.
Tools and Equipment
The spray can is one of the many tools needed to successfully pull the procedure. You will also need gloves. Go for heavy-duty types, which will protect your hands from any damage or injury.
Some of the sprays may have chemicals that can be harsh to your hands. Here, is where the gloves come in handy. Ensure they allow ample hand mobility for comfort.
A mask is another thing to have when you want to create a sound buffer in your vehicle. Some of the products may have a strong smell, which can be quite uncomfortable. The ingredients may also be harmful to you, like the propellant. If you inhale it, you may experience signs of intoxication, such as dizziness.
A mixer is essential if you have a spray that needs premixing before use. This tool is mostly electric and spins fast to stir the material. Such types of sprays have a mixer in their packages for your convenience.
Finally, you need masking tape. It helps in covering the parts of the car that you do not want to coat. You can use it together with old newspapers to cover such parts.
Once you tick most of the products in this list, then you are good to proceed.
Step by Step Application
Follow the below steps to correctly apply the sound deadening spray.
Step 1: Prepare the Surface
The first step is preparing the surface. The area should be clean, with no dirt or rust to get a nice adherence. Strip the spot of any fabric or plastic and use a cleaner to remove any dirt. Rubbing alcohol does an excellent cleaning job.
For rust, you can use sandpaper or similar material to remove the ferrous layer. Follow up by cleaning it. Use your masking tape and newspapers to cover areas that you do not want to soundproof.
Before cleaning, ensure to put on your protective gear.
Step 2: Product Preparation
The intensity of the second step depends on the type of product. If it is a spray, you have to continuously shake it for a minute. The operating temperature should be around 70-100-degrees Fahrenheit. It prevents a fire hazard, as the propellant may be flammable.
If you have the product in a huge container, you premix it. Use a mixer to stir it and get it in the perfect consistency, for application. For products in a container, you can apply them as paint using a brush or put them in a spray bottle.
Step 3: Apply the First Coat
After prepping the material, you now get to the real deal, application. If you are using an aerosol can point the nozzle towards the surface you want to coat. Press the nozzle to release the material, spreading it evenly.
Give it a thick first coat, by using short and even strokes. Do not be too close to the surface. Have a 12 to an 18-inch allowance for the perfect first coat.
If you have a gallon bucket and decided to spray it, use a similar approach. Furthermore, you can use a brush to apply the first coat. Use gentle and precise strokes for the first layer to avoid a patchy finish.
Step 4: Apply Additional Coats
Let the first coat dry and apply additional coats for efficiency. The drying time varies from brand to brand. For some, it takes 15-minutes, while for others it may go up to 24-hours. Check on the instructions to be sure of the drying time.
Apply the succeeding coats the same way you did for the first. Allow for ample drying time between the coatings, for an excellent outlook.
Step 5: Re-assembly
Once the sound deadening material is dry and firmly set to the frame, you can now reassemble the parts. Put them back in the correct order, and you may use heavy-duty automotive glue for a firm grip.
You may paint the surface or prime it as per your desires. Check on the instructions to understand how to go about this.
Step 6: Tidy Up
With everything all set, you tidy up your space. Do away with the masking tape and covering, then clean the surface. Be gentle when tidying up to prevent cracking and chipping. Once done, dry the area and enjoy a soundproof vehicle.
Are Sound Deadening Sprays Better Than Mats?
The other way of soundproofing your car is by using mats. It brings us to the sound deadening sprays vs. sound dampening mats debate. So, which of the two options is better?
Each of them has its benefits and downsides. For instance, the spray is easy to apply, though it is prone to chipping off. Moreover, it is more of a short-term solution. On the other hand, mats are pretty hard to set but are very durable. They are ideal for long-term use.
Mats are also quite expensive than sprays. Removal is a challenging affair and may leave remnants.
Sprays may have a strong odor, especially before they dry.
Looking at their respective advantages and disadvantages, we can say the result is a close tie.
